This International Standard specifies a test method for the determination of the scratch resistance of enamel finishes. The method is based on ISO 1518:1992, Paints and varnishes—Scratch test, but is performed at significantly higher forces.
The value of the scratch resistance that is obtained is a measure of the durability of porcelain enamel finishes when scratched by sharp objects under high forces. The value should not be confused with scratch hardness, a quantity that is measured by the procedure described in EN 101:1991, Ceramic tiles—Determination of scratch hardness of surface according to Mohs.
